A case study at a global pharmaceutical company has been conducted toanalyse how the Hidden Structure method using the Enterprise Architecture Analyses(EAAT) tool, developed at KTH, can be used to visualize the IT architecture and tocreate a better understanding on which applications could increase a risk of therobustness of the architecture if changes was done to them. Also the measure of ITsupport metrics as incidents and changes per system has been analysed to understandif they can be used to understand the robustness of the incident. The tool was used tocreate a model of the enterprise architecture of the company and the analysis showedthat the robustness of the IT architecture was good; the core applications that couldcreate most damage were identified. The analysis of the IT support metrics showedthat it was difficult to use the change records as indicators since the number ofchanges per systems were very few. The incident analysis showed that the systemswith the highest number of incidents were classified as belonging core or peripheralcategory.
